Behavioral and physiologic observations suggest that the injection of local anesthetic is among the most feared or anxiety producing procedures during dental intervention. Discomfort during the injection is currently reduced by pharmacologic or mechanical methods. No technique has proven to be effective for every patient. The VibraJect LLC (USA) was first introduced in 1995 and was developed under the hypothesis that a vibrating needle would stimulate large diameter nerve fibers and thereby close the gate to smaller nerves carrying the pain signal from the injection site. Studies on adult patients have been promising. The purpose of this study is to investigate the efficacy of the VibraJect dental syringe attachment in reducing injection discomfort and procedural anxiety in the pediatric dental population.
